How do you clean a egr valve on a chevy3500 van?

Answer 1

Follow the below steps to clean the EGR valve on Chevy Silverado:

1) Allow the Silverado to cool for a half hour to prevent components under the hood from being too hot. Open the hood by pulling the handle located inside on the lower left side of the instrument panel. Locate the EGR valve; the valve is behind the air conditioner compressor just above the thermostat.

2) Remove the valve using a socket wrench. Loosen the four bolts securing the valve in place. Once the bolts are removed, the EGR can be lifted off the mount.

3) Apply carburetor cleaner to the valve, making sure cleaner is sprayed inside and outside. Apply cleaner to the valve mount as well. For excessive buildup, allow the cleaner to soak the components for five minutes. Remove the deposits and grime using a wire brush and rag.

4) Reinstall the EGR by placing it back onto the valve mount. Replace the four bolts and tighten using the socket wrench and close the hood
